[PD] PD, arduino and sharp range detectors
Hi All, We are having trouble with a PD - Arduino - Sharp IR gp2d12 IR range sensor. everything works for a while, then the arduino just stops and sometimes takes PD down with it. once we had a warning from the OS that there was too much current being sucked on the USB port. we are using three such things, each uses typically 33 and up to 50 mA. This should (according to the Arduino and USB specs) not be too much, but perhaps these are wrong. Any other ideas? I have heard of people using smoothing capacitors on the sharp sensors. Hmm, puzzled in Linz, Tim ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

This should (according to the Arduino and USB specs) not be too much, but perhaps these are wrong. I have built a circuit with six of those sensors on an Arduino Diecimila, it worked fine with external power, but I didn't even try it with USB power because for me 50mA is too much. (At first it crashed sporadically because I was sending too much data through the serial port.) The actual USB port you are using may not be able to supply that much current even if the USB circuit is able to handle it. If it only happens occasionally it's probably because the sensors sometimes pull more than the average current, so a ~100uF capacitor on the power pins would help, but you should really use a separate power supply for the sensors, or just power the entire Arduino externally.

[PD] pix_record and long periods of inactivity
Hi All, another strange property of pix_record. I have been using it to record small clips fine, but now that I have started looking at better quality recording, especially the DV_PAL codec, I have found that I get some problems, I think related to auto usage. the simplest form is: Turn on, wait 60 seconds, record 50 frames (2 seconds) of material, save. Then I get a video that has the first frame still for 60 seconds, then the next two seconds in full frame rate. I only want the important 2 seconds. Any ideas what I might be doing wrong?

[PD] looking for a Workshop person - Arduino, etc
Hi PDers, a friend from the local arts university student union has asked me whether I know of someone who could do a workshop on the Arduino and using it with Max and/or PD. The workshop should happen this semester (up to Feb 2009) for two days or so. The Uni is in Linz, Austria. There is some money for it. This might work well for a travelling musician or artist who is close by, or someone from Czech Rep. or Austria needing a side job. I would find it interesting to also offer them a PD workshop or something similar, perhaps PDP or Gridflow or whatever other bits are cool and sexy this time of the year. It would be good to be biligual (German and English). Either contact me or Jakob at [EMAIL PROTECTED] for further details.

[PD] arduino and bluetooth
Hi Arduinoids, I am using the arduino object with a normal (non bluetooth) Arduino board. When I start up, however, something (I think maybe the comport object) tries to connect with my phone (as a bluetooth device) and the PD patch with the arduino object will not appear until I have said Yes to the request for contact.

Re: [PD] arduino pd os x bluetooth
Thank you Koray. I can confirm that one needs only change the value 57600 to 115200 in the firmata code (to be uploaded to the Arduino board) and in the arduino.pd abstraction. For those who find this later and want to make it work: I suggest making new copies of each of these things if you start to play with them, called e.g. arduinoBT-test.pd that uses arduinoBT.pd and the firmware PdBT_firmware.pde (In a new directory called PdBT_firmware for the Arduino to be happy). Just to help remove the chance of confusion when you go back to the USB version. the firmware PdBT_firmware.pde is opened and only one instance of 57600 needs to be changed. same in the ardionoBT.pd patch. Easy.

Hi David, it also depends upon who you are working with. I tend to work with PD for a number of reasons, however most of my colleagues are Max people who, for a number of reasons, will not be learning a second language any time soon. This is not really a problem as both systems can do most things. Mixing them using OpenSoundControl (OSC) for communication is also no problem. From there it is easy to then mix in almost any language that has an OSC interface; , Python, C, perl, etc. tm On 15/10/2007, at 6:59 AM, marius schebella wrote: Hi David, It depends very much on what you want to do with the program and what the people around you know and use.

(well, pd can crash too). max has a nicer interface. if you want to look into the sourcecode then you have to use Pd.

Re: [PD] Gem and ieee1394 firewire cam on linux debian
Hello Linux / DV users,
Summary: I think I have a fix for the problem with pix_video that
has effected several people on some linux distributions. Please
read on if this matters to you.
Note: this is probably for the pd-dev list, but I am not on it, so I
hope
that one of the PD-dev people can pick up on this and say aha! I can
do this!
I am using a machine with udev on it, so the device names are
not the ones expected by the pix_video object. In particular around
line 213 of videoDV4L.cpp I see that /dev/ieee1394/dv/host0/PAL/in is
being looked at, then
/dev/dv1394.
The error that I think I am seeing is that buf is being set to /dev/
ieee1394/dv/host0/PAL/in
then this is not working (it doesn't exist) and the next attempt to
access /dev/dv1394
is finding that this is a directory (on my machine). So I get the
nonsensical
error:
/dev/ieee1394/dv/host0/PAL/in: Is a directory
On my machine at least, the
devices are /dev/dv1394/0 and /dev/dv1394/1. When I make a link from
/dev/ieee1394/dv/host0/PAL/in to /dev/dv1394/0 then all is well.
Suggested solution: add more possibilities in this series of tests.
snprintf(buf, 32, /dev/ieee1394/dv/host%d/%s/in, devnum,
(m_norm==NTSC)?NTSC:PAL);
if ((fd = open(buf, O_RDWR)) 0){
if ((fd=open(/dev/dv1394, O_RDWR)) 0){
snprintf(buf, 32, /dev/dv1394/%d, devnum); /* new for
debian udev */
if ((fd=open(buf, O_RDWR)) 0){
perror(buf);
return -1;
}
}
}
I am sorry that I am not currently a developer and cannot do this
myself. I am sure someone else out there is clever enough to make it
work
quickly!
I am sure there is a more elegant way to go about this, but I cannot
work
out how to locate the appropriate devices using the ever so clever
udev
system. It seems that people who want to should be able to set up udev
to have special names for special devices. One possibly solution
would be to allow
a message to pass a device name to pix_video, then this device name
would be
used instead of pix_video trying to guess. In that case I might have
been able to
use a openpanel to point pix_video at the correct /dev/dv1394/0.
Perhaps other people who cannot get this to work can try to find out
what
the correct name on their machine is. The names that might work are like
/dev/dv1394, if I ls -l /dev/1394/0 on my machine I see
crw-rw 1 root video 171, 32 2007-08-22 03:42 /dev/dv1394/0
which means I am the right place: the c at the start tells me that this
is a special character device and the major number 171 tells me
(I think!)
that this is a video device.
So if you want to find some other devices that should be looked at in
this opening routine, then perhaps suggest them now so that someone
can add them to the source...
I am also not sure that this way of working through the list of possible
places for the camera and reporting an error about the last one that was
tried and failed is the best. But that's something for another day.
Cheers,
Tim

Hi Kids!
Time for a new adventure. I would like to have a working
firewire camera input for manipulation in Gem on a linux

fine with Kino and dvgrab, so the linux-firewire connection
is all well.
But I am having no luck with pix_video or pdp_v4l. The main problem
seems to be that (apparently) recently the naming conventions
in debian and possibly linux in general were changed. So there is
no more /dev/video0 for the v4l mode, and for pix_video trying to
work directly with ieee1394, I get complaints that /dev/ieee1394/dv/

Is a directory.
Has anyone had more luck? Do I need to going from stable to testing in
some parts of debian? Do I need to use some special somethings?
Looking forward to the d'Oh moment,

Re: [PD] shell script for ieee1394 on debian
Hi Olivier, I seem to be having the problem again that some paranoid program is snipping off the dv.sh script because it might contain a virus! Did you mean the following script: mkdir -p /dev/ieee1394/dv/host0/PAL mknod -m 666 /dev/ieee1394/dv/host0/PAL/in c 171 34 mknod -m 666 /dev/ieee1394/dv/host0/PAL/out c 171 35 I copied this from the article that you linked below. If it is this, then Hurrah! it works. Do you have any idea why it is necessary to create these nodes, while Kino seems to find the devices without any trouble? It would be nice if this just worked out of the box on linux. Cheers, tim On 16/08/2007, at 10:12 AM, Olivier Heinry wrote: WARNING: This e-mail has been altered by MIMEDefang.

Re: [PD] Gem and ieee1394 firewire cam on linux debian
Hi Georg, Thanks for your reply. When you say quite some time ago when was that approximately? I see that in Dec 06 Ico Bukvic was having the same problem, but the thread stops on the PD list. Anyway, I tried your suggestion. When I try this I get Bad argument for message 'driver' to object 'pix_videoNEW' Seeing as when I send |driver 1( to pix_video I receive the error message that refers to /dev/ieee1394/dv/host0/PAL/in, or host1 if I have send |device 1( message, then I would guess that the external is trying to do the right thing. I must mention that /dev/ieee1394 does not even exist in my hierarchy. Perhaps something has not been created for this. However, Kino and dvgrab work out of the box so the basics are all working fine. Only PD is trying to do the wrong thing. Hmmm, any further ideas?

Re: [PD] [SPAM?] [LOW] fixing distortion on surface
We used one approach for SPIN: http://www.timesup.org/spin where we did render to texture of the image we wanted to be seen, then placed this texture on a model of the screen and filmed it from a camera placed where the projector was. in 2000, when we did this, it was only possible to do this sort of thing on consumer grade PCs using DirectX, so we had to go down that path. I think this is now doable in general OpenGL stuff, but no idea how. The latest version of software for SPIN was made in , so it would be probably relatively easy to modify their code for some other surface. I make it sound a bit trivial, but it isn't quite. But it is also a lot easier than it was originally for us.

Re: [PD] pix_multiblob cpu usage
chris, are you using it on OSX? Was it hard to compile?

[PD] pix_record inverting image
Hi all, I am using pix_snap and pix_record to get a series of images with decoration into a video file. This is (surprisingly enough!) working already, but with one interesting feature: the recorded videos are vertically inverted! top-bottom exchange... Hmm, any ideas what that might mean? I am using yesterday's build for OSX PPC from .hc. The problem seems to lie with pix_snap: if I connect the input pix_video straight to pix_record, then it goes through right, gets recorded right, all is well. I build a capture with pix_snap. If I look at the texture coming out of pix_snap by pix_texture-ing it onto a rectangle, then it looks right. It just gets turned upside down when it gets recorded. Any ideas would be great. No huge loss, I am sure it a simple post-processing thing to make it look right, but I would like to know what is going wrong tim ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] text into pix
Hi Roman, Okay, I had contemplated this and though that it must be possible to do this easier. But No! This seems somehow like a hack, but I suppose pix_ things are there for image manipulation, not image creation... I am using OSX so there is currently some problem with GEM and fonts and PD and...hmm... so it remains undoable anyway :- But thanks: I will simply build a few simple graphical objects to transfer the information, then use pix_snap to get images for recording. Thank you muchly!

Or is there a better solution? don't know, if there are various solutions, but you can convert the framebuffer into a pix again using [pix_snap]. either you can grab both together, the video and the text, so that you display the text already upon the video, or you could grab the text separately (in a free area of the gemwin) and use [pix_mix] to merge the text-pix and the video afterwards. the former is possibly simpler to implement, but since you are applying a pix as texture in order to display it in opengl and then converting it back to a pix again, this might introduce interpolation artefacts. however, if you have alltogether in one pix, you can simply record it using [pix_record]. roman Cheers, tim ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/ listinfo/pd-list ___ Telefonate ohne weitere Kosten vom PC zum PC: http:// messenger.yahoo.de ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] PD CHAT
Hi, I have done a series of small performances where a telnet-based chatroom has been the performance space and PD makes sounds in response to actions there. The simple explanation is to use netcat (nc) to communicate with a chatroom, the output then being fed via a small sed script via pdsend to PD, receiving via a netreceive object. On the other side I was using some pdreceive (on a linux machine, now I use OSX and I cannot find it!) to take messages from PD and feed them into netcat. Some playing around last week seemed to show that netreceive no longer needs the closing semicolon ; on messages, so in some cases it may be possible to avoid the sed script and simply pass the output of nc direct to pdsend. I haven't tried this yet. If this is all gibberish, I can dig out some examples on how to use it all. It worked a few months ago when I last tried it... cheers, tim On 04/02/2007, at 5:03 PM, juto aviten wrote: another simple questions : I try to chat in PD and to catch result of the chat... can't find any object for this... does something exist in this idea? thanx juto ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/ listinfo/pd-list ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
